This issue is about showing a wrong icon.
It is only about the identification of system or device batteries in UPower.
Please search other bugs or report a new bug for your problem.
BTW, Logitech wireless mouse seems to have some specific protocol to detect the battery remaining power information in Logitech wireless mouse. Even a non-chargeable battery has its remaining power information.
